Pulse, respiration, temperature, and blood pressure or “vital signs” are routinely performed as part of the cardiovascular assessment and considered the earliest objective fundamental aspect of the physical examination. The term “vital signs” specifies the presence of those bodily functions considered an essential component of life. These signs are historically important to recognize and provide important insights into methods and techniques for diagnosing various disease states. These objective findings along with other key components assist clinicians in narrowing the differential diagnosis or determining the cause of the underlying disease. Included in this discussion are signs found in patients with hyperthyroidism as detected by blood pressure and temperature as well as bleeding disorders that may be surreptitiously discovered when blood pressure is measured using a sphygmomanometer cuff. Additionally, some of these signs may be clinically useful providing important insights into potential mechanisms of disease. Thus, it is important that clinicians learn how to properly perform, identify, and apply these signs. Included in this chapter on vital signs is a brief historical background of the person who described the sign, the sign as originally described, and if available, the sensitivity, specificity, and predictive values of the signs.

Wax modelling has been used since ancient times with its first application in art in the fifteenth century involving famous artists with knowledge of anatomy. It was only in the seventeenth century that coloured ceroplastic began to be used for teaching anatomy as valid alternative to dissected human bodies, including also neuropathological. The origin of this scientific approach was born in central Italy, in Florence and Bologna in the eighteenth century, and immediately spread to other Italian cities, and Europe, and throughout the rest of the world. Wax neuro-models were shown as artefacts and destined to train young doctors in anatomical knowledge. Nowadays, wax is often considered an old-fashioned art form but what is not well known is that wax has a useful therapeutic application in medicine, with a particular emphasis in neurosurgery.
This paper describes a possible structure for the pamcrystalline form of the sodium salt of deoxyribonucleic acid. The structure consists of two DNA chains wound helically round a common axis, and held together by hydrogen bonds between specific pairs of bases. The assumptions made in deriving the structure are described, and co-ordinates are given for the principal atoms. The structure of the crystalline form is discussed briefly. I~TR~DUOTI~N The basic chemical formula of DNA is now fairly well established. It is a very long chain molecule formed by,the joining together of complex monomeric units called nucleotides. Four main types of nucleotides are found in DNA, and it is probable that their sequence along a given chain is irregular. The relative amounts of the four nucleotides vary from species to species. The linkage between successive nucleotides is regular and involves 3'-5'-phospho-di-ester bonds. Information about the three-dimensional shape is much less complete than that about its chemical formula. Physical-chemical studies, involving sedimentation, diffusion and light-scattering measurements, have suggested that the DNA chains exist in the form of thin rather rigid fibres approximately 208 in diameter and many thousand of angstroms in length (Jordan
